Application filed August 3G, 1912. Serial No. 717,949.

To all? who/m. t may conc-em: l

ijeit known that. l, Geenen B. STEWART, a

citizen of the United States, residing atA Pittsburffli, in the counts1ofAllegheny and State of Pennsylvania, have invented a newl and uso/frNozzle for Vacuum-Cleaners, of

Weich lthe following is a specification.

The present invention relates to improvements in nozzles for Vacuumcleaners, the

present structure being especially designed nozzle'is placed intoact-ire' relation thereto.

With' the. foregoing. and other objects in View which will appear as thedescription proceeds, the invention resides in the com'- bination andarrangement. or part-s and 1n the details of construction hereinafterdei' scribed and claimed, it being understood that changes in theprecise embod1n1e;':t of the invention herein disclosed can be made Wit-in the scope of what is claimed Without departing from the spirit ofthe invention.

In the drawings-Figure l is a side ele#l portion or member. FigS is aplan View of the exchange board engaging member.

leferring'totlie drawings, the numeral l designates the nozzle headwhich is adapted to have the 'end 2 connect-ed to a suction hose (notshown), and carri `l by the head at diametrically opposite pointsaretlie two arms 3 carrying each guiding sleeved. Mounted forv slidingmovement in the sleeves 4 are the two rods Eeacli4 one of'whicli isprovided Withfthe limiting head and lia.Q its other end connected to thelug 6 of the exchange Vboard engaging iiieinbei' or mouthpiece 7.' Thisis preferably madeot an invsulating material .so as to avoid any shortcircuiting When-used in connection with the exchange board.

The mouth-piece 7 is provided with a plurality of inlet apertures 8 andin order to tliig. .I

` provide a means to prevent injury to the exchange board and :it thesame time to provide a chamber upon. the exchange board engaging side ofthe mouth-piece 7, a rim 9 of felt or rubber is carried as shown.

In order to hold the mouth-piece 'i' away from the nozzle l, as shown inFig. l, the coiled springsr l0 are disposed upon the rods and engageatone end the sleeves' 4 while at the other end the lugs 6,

When it is desired to operate the present device, the mouth-piece ispresented to the exchange boardwitli the rim 9 thereagainst 'and by aslight pressure uponthe nozzle 1, the two springs 10 are compressedasshouin' in Fig. 2, until the nozzle l engages the mouth-piece 7, thusconfining the suction action tothe perforated portion of the mouth piece7 and thus only acting upon the exchange board when the nozzle l' ispressed inoutlilpiec-eis first positioned upon-the -exchange board andnov suctionl action is perthe position assliown in Fig. 2. 'It is alsoevident that by reason of the springs 10 the release of the nozzle 1will permit of an automatic adjustment of' the members from the positionas shown in Fig. 2 to that shown in F 1, thus automatically relievingthe mouth-piece 7 of any suction .action when the tool is being removedor released.

W'liat is 'claimed is:

1. Ina tool for vacuum cleaners, the conibination of a nozzle having aninlet -and an to 'and from the inletof said nozzle, and 'resilient meansto normally hold the mouthpiece away. from said inlet.

2.. In a tool for vacuum cleaners, the coinbination of a nozzle haringan inlet and an outlet, a perforated mouth-piece, and means carried bythe nozzle and mouth-piece ior resiliently connecting the inoutl1-pieceto the nozzle for movement to and-from the inlet thereof.

In -a tool for 'vacuum cleaners, the couibination of a nozzle i: ing aninlet and an outlet, a, plurality' of guiding arms carried by saidnozzle, a mouth-piece, a plurality of rods slidably mounted in said armsand con'- a spring mounted upon each rod for resiliently holding theinoutli piece away from the -inlet'end .ot the nozzle.
